ubuntuftpftp-clientpamvsftpd

why is my pam_userdb.so missing?

I want to use vsftpd to create a guest user , so I appended these to /etc/pam.d/vsftpd:

auth    required /lib64/security/pam_userdb.so db=/etc/vsftpd_virtual_accounts
account required /lib64/security/pam_userdb.so db=/etc/vsftpd_virtual_accounts

But I can't find the pam_userdb.so file in /lib64/security and /lib/security.
And find / pam_userdb.so shows "no such file or directory".

How can I get the pam_userdb.so file?

Solution

  • Finally I found it in /lib/x86_64-linux-gnu/security
